The TS 420 cut-off machine delivers a unique blend of performance and efficiency, helping you work longer and more comfortably with a 14’’ cutting wheel. It features stratified charge engine technology that cuts fuel consumption by 20% and exhaust emissions by 50%, lightweight assembly, newly designed anti-vibration system and the new long-life X2 air filtration system to reduce maintenance. This unit can be hand-operated or mounted on the FW 20 cart (sold separately) for improved precision and comfort.
2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.
Pre-separation air filtration system
STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
Semi automatic V-belt tensioning
Light, consistent re-tensioning increases the service life of the belts and shaft bearings.
The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.
This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
